Fig. 3 Expression of zebrafish cyp11a1 in adult organs. (A) Whole-mount in situ hybridization of adult brain. OB, olfactory bulb; Tel, telencephalon; Hyp, hypothalamus; PG, preglomerular area; ON, optic nerve. (B,C) Ovary. (C) Section of (B). Expression of cyp11a1 is located in oocytes and the granulosa/theca cell layer. Arrow in (C) indicates granulosa/theca cell layer, and arrowhead the zona pellucida. (D,E) testis; (E) is a higher magnification of (D). Arrows in (E) indicate Leydig cells. Scale bar: 1 μm. (F) Northern blot analysis detects expression of cyp11a1 in adult ovary, stage V oocytes and early cleavage stage embryos.
